A Proposal on Adaptive Service Migration Framework for Device Modality Using Media Type Conversion

tance service, which can follow a user and support his/her work in any situations. In other words, application software on our framework can migrate from a device to another; even their hardware architectures are heterogeneous. In the vision, user interface (UI) is one important factor to provide fine usability and seamless user experience of the service to users. Since various kinds of use case could be considered, UI should autonomously adapt to the working environment without annoying the user. Therefore, in this paper, we analyzed possible use cases and discussed approaches to support the UI adaptation. Based on the UI technology study, we found that one important factor have to be considered in our scenario: That is diverse modalities, which comes from supporting heterogeneous devices as the service migration platform. Since we also target devices of which modalities are different from ordinary PCs, UI should change its computer-human interaction model after the migration. To address this challenge, we propose an adaptive service migration framework, which supports the UI adaptation. We also report results of several experiments on the framework.
